Proceeds from “The Girls of Ryanair” calendar, which features scantily-clad female flight attendants, will go to DEBRA, which provides support for patients suffering from epidermolysis bullosa (EB), a genetic skin condition.

The charity was chosen from nearly 400 applicants, and Ryanair said it hopes to raise around £85,000.

The calendar costs £8.50 and can be purchased on board Ryanair flights, from DEBRA’s charity shops in Spain and Ireland, or on the airline’s website (www.ryanair.com).

Stephen McNamara, a spokesman for Ryanair, said that the money raised would be used to take 50 children with EB, and their families, on a holiday to Malaga, where they are provided with support by members of the DEBRA team.

Jimmy Fearon, DEBRA’s chief executive, said: “Ryanair’s donation will help us to deliver a once in a lifetime opportunity for 50 families to enjoy a holiday, with professional care and assistance on hand to allow parents and children time to rest and enjoy their precious time together.”
